PAPER-FOLDER.

SPECIFICATON foaming part of Letters Patent No. 389,192, dated September1ll 1888,

Application filed November 19, 1887. Serial No. 255,600. (No model.)

To all whom it may concern,.-

Be it known that l, LEONARD E. BEooKEs, residing at Chicago, in thecounty of Cook and State ot' Illinois, and a citizen of the UnitedStates, have invented a new and useful Improvementin Paper-Folders, ofwhich the fol lowing is a specification, reference being had to theaccompanying'drawings, in which- Figure 1 is a side elevation. Fig. 2 isa cross-section.

This invention relates t paper-folders in which the folding-blade has amovement on the are of a circle, which, however,is nearly a verticalact-ion for the distance which the knife is to move, and is primarilydesigned for use with folding-machines for printing-presses, but can beused for other purposes; and it has for its objects to compensate .forthe slight curve in which the blade moves, so that when the blade entersthe bite of the folding-rollers it will have approximately a directforce in line with such bite, and its nature consists in the severalparts and combinations of parts hereinafter described and claimed asnew.

In the drawings, c represents the blade, which may be of any of theordinary forms of construction. This blade a is attached by screws b tothe outer or lower ends of rods 1 and 2, and by screws c to a cross baror piece, 36, which piece runs from arms extending out from collars 3and 4, which collars are mounted upon a suitable cross-shaft, 5, whichis sup ported in suitable boxes at each end on the cross-piece 7, asshown in Fig. 2, which crossA piece is formed with or secured to the endpiece, (i. Extending up from each cross-piece 7 is a supporting-ear, inwhich is journaled a shaft, 8, which shaft at one end has a journal, 21,and at the other ajournal, 22, whichjourna122 projects beyond the end ofthe plate; and, as shown, this shaft at one end has an abutting collar,11, and at the other end au abutting collar, 12, and, as shown, theshaft 5, supporting the collars 3 and 4, is provided at one end with ajournal, 19, and at its other end with ajournal, 20, and with abuttingcollars 13 and 14 at the respective ends. These collars 13 and 14 andthe collars 11 and 12 prevent end movement of the respective shafts towhich they are applied. The shaft 8 has secured thereto by suitablecollars or rings arms 9 and 10, to which thc rods which support theblade are connected. The shaft is provided at one cnd with collars and16, and at the other end with collars 17 and 18, with a spacebe tweenthe respective collars,between which co1- lars are located the rings orhubs 3 and 4, 3 being between the collars 17 and 18, and 4 between thecollars 15 and 16.

A series of leading-tapes, 23, is located below the folding-blade, and acorresponding series of tapes, 24, is located below the tapes 23, andthese tapes 23 and 24 are arranged to lead over the folding-rollers 25and 26 and deliver the paper to the rollers. The foldingroller 25 isprovided with a `journal, 29, at one end, and at the other end with ajournal, 30, and each journal is mounted in a suitable box located inthe support 34, attached to the crosspiece ofthe iframe, and the journal31 of the foldingroller 26 is supported at each end in a box, 33,located in a slot in the support 34, and in this slot, back ofthejournal-box, is a coiled spring, 32, which allows the box andfolding-roller to yield whenever required.

Attached to the journal 22 of the shaft S is an arm, 28, to which isconnected by a pin, 35, thc end ofthe pitman or connecting-rod 27, whichrod at its other end is connected with an operating mechanism, by whichit can be given a reciprocating movement to move the arm 2S and rock theshaft 8, and through such shaft move the arms 9 and 10 to operate therods 1 and 2, and move the folding-blade to or from the folding-rollers.

The cross-rod 36, to which the folding-blade a is attached by screws c,is supported in the outer ends of the arms carried by the collars 3 and4, and is held in position by nuts 37 and 38 and lock-nuts 4S and 49, bywhich means the blade is given a firm and strong support. The outer endof the arm 9 hasasocket, through which passes a bolt, 45, having at itshead end an eye and socket portion, 40, through which the screw-threadedend of the stem 1 passes, and this stem is adjusted for the properposition of the folding-blade by lock-nuts 43 and 44, and the arm 10 hasa corresponding socket, through which passes a bolt, 46, having an eyeor socket head, 39, through which passes the screw-threaded end of thestem or rod 2, which is likewise adjusted for the posit-ion of thefolding-blade by locking-nuts 41 and 42. The tapes 23 and 24 run overpulleys, which pul- IOO leys are mounted on a shaft supported in thebracket 47, attached to the frame of the machine.

The arm of each collar or hub 3 and 4 is formed in two portions, one ofwhich is secured to the hub, and the other has asocket, in which the endof the cross-bar 36 is secured,and these portions are connected by aturn-buckle, 50, located between set-nuts 5l and 52 on the ren spectiveportions of the rod, so that by turning the buckle 5() the rod as awhole can be lengthened or shortened to move the cross-,bar 36 out or into bring the edge of the foldingblade in line with the bite of thefoldingrollers when performing its work, and these arms and the mannerof connecting them with the cross-bar 36 and the arms 9 and 10 and themanner oi' connecting them with the stems or rods 1 and 2 form aparallel motion, by i which the blade is raisedand lowered in a mannerto bring its actingen-d inadirect line with the bite of thefolding-rollers, and it will be seen that by means of the adjustingdevice by which the blade is supported andconnected 5 with the parallelarms the blade can be adjusted in or out, or up or down, as may berequired for the correct position in use, and at the same time therelation between the arms is not materially changed; and, furthermore,by

3 this manner of supporting the blade the-actu- 5 just-ed in itsposition to line with the foldingY rollers by means of theconnecting-arms of the cross-bar 36, and is adjusted for the limit ofits motion by means of its stems or rods 1 and 2, and when adjustedproperly the rod 27 is reciprocated to move the arm 28,which rocks v theshaft 8 and moves the arms 9 and 10,Which arms, through connecting stemsor rods 1 and 2, give the proper thrust to the blade, and the blade,through its supporting-bar 36,moves the arms ofthe hubs or collars 3 and4 in unison with the movements of the arms 9 and 10.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the folding-blade, of the rods 1 and. 2, therocking arms 9 and 10, adjustably connected with said rods, the shaft 5,having collars` 3 and 4, provided with adjustable arms, the cross-bar36, j ournaled in said armsandmttachedto the folding blade for thepurpose of changing the line ot'` descent of said blade, and means forsupporting and actuating. the rocking arms, substantially as described.l

2. The combination, with folding-rollers, of a folding-blade carried bythe adjustable con` meeting-bar, and the rod 36, carried in adjustablearms connected with the collars 3 and 4, and parallel` moving arms foroperating the connecting stems or rods, substantially as described.
